The specific embodiment
As shown in Figure 1-Figure 3, the embodiment of wheeled drilling depth measuring instrument of the present utility model, while comprising use, be installed on wheeled sounding gear 30 and boring depth measurement main frame 31 on rig, described wheeled sounding gear 31 comprises the fixed mount 8 being fixedly mounted on rig 32, fixed mount 8 is connected with fixed head 7, fixed head 7 is fixed with guide protective tube 19, in guide protective tube 19, only revolve guiding movement along rectilinear direction and be equipped with the axis of guide 6, the Axis Extension direction of the axis of guide 6 is consistent with its moving direction, the axis of guide 6 only revolves guiding movement by locating shaft 17 with the axial elongate slots on guide protective tube 19 and coordinates, linear bearing 16 is also housed between the axis of guide 6 and guide protective tube 19 and the axis of guide 6 is applied to the spring 20 of the active force that presses to drilling rod.The axis of guide 6 one end coaxial rotation are equipped with rotary wheel frame 3.Between rotary wheel frame 3 and the axis of guide 6, be provided with and gather the angular transducer 5 of rotary wheel frame 3 with respect to the rotational angle signal of the axis of guide 6, in being provided with between rotary wheel frame 3 and the axis of guide 6, establish the thrust metal 4 of thrust ball bearing 13, angular transducer rotating part 51 is connected with rotary wheel frame 3, angular transducer standing part 52 is connected with the axis of guide 6, and angular transducer standing part 52 is specifically fastened on by clamp nut 14 by angular transducer fixture 15 on the axis of guide 6 of an axially-movable and can not rotates.Therefore in the time that angular transducer rotating part 51 rotates, can measure real-time angle and pass the signal on boring depth measurement main frame 31.
On rotary wheel frame 3, be rotatably equipped with runner 2, the pivot center of runner 2 is vertical but non-intersect with the pivot center of rotary wheel frame 3, between the pivot center of the pivot center of rotary wheel frame 3 and runner 2, there is the eccentric distance of setting, object is to guarantee can produce all the time the turning moment to rotary wheel frame 3 when runner 2 does compound movement on drilling rod 1, and this turning moment can force rotary wheel frame 3 consistent with the movement locus angle of drilling rod 1.And be provided with and gather runner 2 around the displacement transducer 11 of the swing offset of its axis, displacement transducer fixture 112 is fixed on rotary wheel frame 3 by displacement transducer holder 12, between runner 2 and rotary wheel frame 3, be provided with rolling bearing 9, on runner 2, be connected with the power transmission shaft 10 with its rotation coaxial, displacement transducer tumbler 111 is just connected with power transmission shaft 10, in the time that displacement transducer tumbler 111 rotates with respect to fixture 112, fixture 112 gathers the swing offset signal of runner 2 and is sent to boring depth measurement main frame 31.
Above-described embodiment in use, wheeled sounding gear 30 is arranged on the clamper front end of rig by fixed mount 8, and the runner 2 that makes wheeled sounding gear 30 is in radially the top of drilling rod during with drilling rod laminating, wheeled sounding gear is in depth measurement process, and the real-time displacement △ L of displacement transducer 11 is always consistent with contacted drilling rod 1 componental movement real-time track evolute length.The motion particle that the real-time angle signal α of angular transducer 5 contacts in runner 2 is always consistent with respect to the angle angle of drill rod axis.The following is the motion state of drilling rod in the process of drilling, existing classification describes:
Drill in process whole, drilling rod motion mode is divided into four kinds:
1, inactive state.Runner compresses drilling rod, and the relative drilling rod of runner and rotary wheel frame is static, and non-displacement and angle change.
2, drilling rod only can rotate bar or moves back bar.Now the motion state of drilling rod is that a certain particle of external surface moves in a circle along axis.Under this state, runner 2 is along the axis direction rotation parallel with drill rod axis.Rotatablely move and angle α=0 ° of drill rod axis.According to sinusoidal algorithm sin0 °=0 of triangle law, therefore although now runner 2 produces displacement, under this state, drilling depth is 0.
3, drilling rod rotation axially-movable simultaneously state.Now to be a certain particle of external surface move along the axis line of spinning the motion state of drilling rod.Runner 2 is followed and is rotated and gather the helix length of run △ L of section sometime.And runner 2 axis and drilling rod 1 axis angle α ∈ (0.90) U(-90.0 that angular transducer gathers).According to sinusoidal algorithm sin α ≠ 0 α ∈ (0.90) U(-90.0 of triangle law).Drilling depth L=△ L × sin α ≠ 0 now producing.In the time of drilling depth L > 0, it is rotary drilling.In the time of drilling depth L < 0, for bar is moved back in rotation.
4, drilling rod does not rotate, and state vertically only seesaws.Now the motion state of drilling rod is that a certain particle of external surface does rectilinear motion along axis.Under this state, runner 2 is along the axis direction rotation vertical with drill rod axis.Rotatablely move and angle α=± 90 ° of drill rod axis.According to sinusoidal algorithm sin ± 90 of triangle law °=± 1, so time runner 2 positive-displacement be drilling depth, negative sense displacement is moves back pole length.
Above-mentioned four kinds of motion states can frequent and irregular appearance in rig is drilled process.Boring depth measurement main frame can carry out analytic operation in real time according to displacement and angle signal, carries out the cumulative of drilling depth or successively decreases.
In other embodiment of wheeled drilling depth measuring instrument of the present utility model, also can not hole depth measurement main frame and only have wheeled sounding gear, now can carry out data processing by a supporting computer.
